Q: how do u change your mbps to 256 an your computer?
A: mbps is how fast your internet is, it means mega bits per second, it is impossible to change it, unless you get a diffrent internet, but if you are talking about color then if you are on windows xp then you cannot change it to 256 only 16 and 32 bit. But if yo want to change it just for an individual program then right click on the program then go to properties and choose compatibility then you have your options. But if you are talking about storage, or memory I have no clue what your talking about.
